OnSemi at Deutsche Bank's 2025 Conference: Strategic Focus on Growth

On Semiconductor (ON) presented a cautious yet strategic outlook at Deutsche Bank's 2025 Technology Conference, highlighting market stabilization despite geopolitical uncertainties. The company is actively exiting lower-margin businesses, representing 5% of 2025 revenue, to intensify focus on high-growth sectors such as silicon carbide for EV/PHEV, the high-margin Treo analog mixed-signal platform, and AI data center solutions. While current gross margins are impacted by underutilization, OnSemi targets a 50-53% gross margin range and expects market conditions to improve in H2 2025, anticipating a return to top-line growth in 2027 driven by these strategic investments.

Analysis

On Semiconductor (ON) is actively navigating a cyclical downturn by executing a clear strategic pivot towards higher-margin, differentiated products, as detailed at Deutsche Bank's 2025 Technology Conference. While near-term gross margins are depressed by a significant 900 basis points due to factory underutilization, management is engineering a structural improvement by exiting lower-margin businesses, which will represent a 5% headwind to 2025 revenue repeating in 2026. This deliberate pruning is designed to enhance the product mix and accelerate the path to a 50-53% gross margin target. The company's future growth is anchored in three key areas: its technologically advanced silicon carbide devices winning share in both EV and plug-in hybrid markets; the new Treo analog mixed-signal platform, which boasts 60-70% gross margins and is already generating revenue ahead of schedule; and an expanding footprint in AI data center power solutions. Although management remains cautious on a broad market recovery due to geopolitical factors, they anticipate stabilization in the second half of 2025 and a return to top-line growth in 2027, once the strategic exits are completed.

Key Decisions for Investors

• Investors should evaluate ON Semiconductor on its long-term strategic transformation towards a higher-margin entity, looking past the cyclical downturn and the planned 2026 revenue attrition which appears to be a calculated trade-off for improved profitability.
• Monitor the revenue ramp and design wins from the high-margin Treo platform and AI data center solutions, as these are critical validation points for the company's ability to achieve its 50-53% gross margin target.
• Recognize that the timeline for margin expansion is extended, with short-term improvements heavily dependent on a market recovery to drive higher factory utilization, which constitutes a primary execution risk.
• Consider the company's asserted competitive advantage in silicon carbide, based on device technology rather than substrate supply, as a key factor that could sustain pricing power and share gains in the automotive sector.
